POMA: Pattern-Oriented and Model-Driven Architecture

Abstract

The proposed pattern-oriented and model-driven architecture (POMA) architecture illustrates how several individual models can be combined at different levels of abstraction into heterogeneous structures, which can then be used as building blocks in the development of interactive systems. This chapter presents the key concepts, an overview, justifications, and specifications of the proposed POMA architecture, a detailed description of architectural levels and categories of patterns used in the proposed POMA architecture, and a detailed description of five levels and categories of models used by POMA. First, we describe the model categorization as well as the key concepts of POMA. We detail POMA while comparing its architecture with N-tiers architectures, pattern-oriented design and architecture (POD), and model-driven architecture (MDA). We describe the architectural levels and categories of patterns including pattern composition rules (i.e., the relationships between pattern considered in this architecture). We describe the pattern mapping rules that enable one to obtain the final models of the proposed architecture. Finally, we define model transformation rules which apply for each type of model, [POMA.PIM] (Platform Independent Model) or [POMA.PSM] (Platform Specific Model). These rules build a relationship between models of each category, i.e., models [POMA.PIM] and [POMA.PSM].
